RFR: 8303691: Fedora based devkit build should load more packages from archive location

[Christoph Langer]

When building Fedora based Linux devkits, rpm packages are downloaded from locations at the Fedora project.
The latest/active versions reside under https://dl.fedoraproject.org while older, archived versions live at https://archives.fedoraproject.org.

It seems more releases have been archived in the meanwhile, so e.g. a build based on Fedora 27, which is currently marked as default, would fail.

I suggest to add a variable `LATEST_ARCHIVED_OS_VERSION` in the make file that denotes the Fedora version up to which a download would be attempted from archives. For later releases, the download is done from dl.
